Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.
